    摘要： A method and apparatus for connecting a user equipment (UE) to a wireless communication network such as a 5th generation network. The network supports node-level tunnelling. Node-level tunnels can be pre-configured prior to receipt of UE attach requests. The tunnels can be shared by plural UEs, flows, or services. A policy function is connected to a network management function and performs tasks such as applying constraints to the node-level tunnels. A session management function pre-establishes node-level tunnels based on policy information from the policy function. Operations of network elements such as the access network node and user plane function to handle UE attachment, session establishment, and handling of mobile-originated and mobile-terminated traffic are described. Also described is a method and apparatus for packet transmission in which packets are processed according to an identified tunnel type. The tunnel type can be identified using a field in the tunnel encapsulation header.

    摘要： An aspect of the disclosure provides for a method for user equipment (UE) internet protocol (IP) address management. The method includes sending by an application function (AF), a request to a policy control function (PCF), the request including information identifying traffic and an indication that a UE IP address associated with the traffic should be preserved. The method further includes sending by the PCF, to a session management function (SMF) being responsible for managing a Protocol Data Unit (PDU) session associated with the traffic, a policy and charging control (PCC) rule including the indication. In some embodiments, the request is sent by the AF to the PCF via a network exposure function (NEF). In some embodiments, the method further includes managing, by the SMF, the UE IP address according to the PCC rule. In some embodiments, the managing includes preserving the UE IP address for a PDU session associated with the traffic. In some embodiments, the preserving includes preventing reselection of a protocol data unit (PDU) session anchor (PSA) to which the UE IP address is associated.

    摘要： Methods, systems and architectures are described which provide at least one aggregated tunnel protocol, in addition to the existing per PDU session tunnel protocols (1, 2, . . . N). When the UE requests a new PDU session or a new QoS flow, the SMF may establish a Per PDU Session Tunnel to serve this PDU session. Alternatively, an Aggregated Tunnel may be selected to serve the PDU session or to serve the QoS flow. When a packet from a UE arrives, the receiving network function can send this packet either using a per PDU session tunnel protocol or aggregated tunnel protocol.

    摘要： Aspects of the disclosure provide a system and method used for allowing a path selection or reselection (hereby (re)selection). In some embodiments data packets for a session between a UE and an application system (AS) can utilize a pre-established user plane path between the AS and an access node (AN) which serves the UE. This can allow for faster session set-up times as a new user plane (UP) path need not be established for every new session if existing UP paths can be utilized. Some embodiments allow an application aware (re)selection of the user plane.
